Texas Instruments provides DSP algorithms for the OMAP 3 platform used in a
2 
number of devices like beagleboard, Nokia N900, and Nokia N9.

The gst-dsp project aims to provide GStreamer elements to take advantage of





5

those algorithms. The list includes video/image decoders and encoders.

7

Unlike other similar projects there are no dependencies (no openmax, no





8

libtidspbridge).

10

The features include:





11






12

 * video decoding (MPEG-4, H.263, H.264, WMV)





13

 * video encoding (MPEG-4, H.263, H.264)





14

 * image encoding/decoding (JPEG)





15

 * zero-copy





16






17

The advantages over other solutions are:





18






19

 * simpler code (5k vs 50k)





20

 * better performance (4x)

== building ==





23






24

There are no dependencies, so just:





25






26

 ./configure





27

 make





28






29

If you are using an old version of TI's dspbrdige driver:





30






31

 DSP_API=0 ./configure





32






33

== tidsp ==





34






35

You'll need a kernel with tidspbridge driver, the DSP firmware in /lib/dsp, and





36

the DSP running a proper baseimage (baseimage.dof).
